IIS module Creatng AppPools in multiple manifests

I'm organizing my manifests by server build types, so server A has one manfiest, server B has another. Server A and Server B both happen to have an apppool named product. This doesn't pose a problem until I try to apply both manifests to a single server type in dev. I get an error that the app pool is already declared in another manifest. Is there a way to work around this?
